Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a luminaire and a control method of luminaire capable of changing light color of illumination light by using a filter for changing the light transmittance without imposing a discomfort to users.SOLUTION: The luminaire include: a light source 11 constituted of a solid light-emitting element; a filter 12 disposed at the light output side of the light source 11, which changes the light transmittance; and a control section 20 that controls the light output from the light source 11. When the light transmittance of the filter 12 changes and when the color of light from the light source 11 transmitting the filter 12 changes, the control section 20 controls the light source 11 to output the light so that the light synchronizes with changes of the light transmittance of the filter 12 and has a negative correlationship. 【課題】光透過率を変えることのできるフィルタを用いて照明光の光色を変化させる場合であっても、ユーザが違和感を感じることのない照明装置及び照明装置の制御方法を提供する。【解決手段】固体発光素子によって構成された光源１１と、光源１１の光出射側に配置され、光透過率を変えることができるフィルタ１２と、光源１１の光出力を制御する制御部２０とを備え、制御部２０は、フィルタ１２の光透過率が変化してフィルタ１２を透過する光源１１の光の光色が変化した場合に、フィルタ１２の光透過率の変化と同期し且つ負の相関関係を有するように光源１１の光出力を制御する。【選択図】図７
